I am using ArcGIS server 10.6. I had to unregister my web adaptor for some reason. I have re-installed the web adaptor and configured to use server application. I am able to connect to the server from other machines on network using computer name but getting issue while using IP address to connect .
Any help will be delightful. Also I have mapped server local IP with and public IP to use this globally.
I am not sure changing web adaptor will have any issue with mapping.

Server machine was not allowed to be accessed from outside network due to firewall configuration. However, I didn't made any changes in firewall but still firewall rules got changed may be due to window update.
Configuring firewall again allowed connection to server.
